Q: Why should we invest in this multi-platform OMS? A: See 0-FOR-INVESTORS/business-case.md for detailed ROI analysis, market opportunity, and competitive advantages.
Q: What's the implementation timeline? A: See 0-FOR-INVESTORS/roadmap.md for phase-based rollout across platforms.
Q: How does this reduce operational costs? A: The architecture enables centralized order processing, reducing manual work by 70-80% across platforms.
Q: How does the system scale? A: See 1-FOR-ARCHITECTS/scalability.md for load distribution, caching strategy, and performance targets.
Q: What's the data consistency model? A: See 1-FOR-ARCHITECTS/data-model.md and integration-patterns.md for eventual consistency patterns with Kafka.
Q: How do we handle security across platforms? A: See 1-FOR-ARCHITECTS/security-architecture.md for OAuth 2.0, encryption, and compliance strategies.
Q: How do I get the development environment running? A: See 2-FOR-ENGINEERS/setup-local-dev.md for Docker setup and quick-start guide.
Q: What are the API endpoints? A: See 2-FOR-ENGINEERS/api-reference.md for complete REST API documentation.
Q: How do we add a new platform? A: See 4-COLLABORATION-GUIDE/contributing.md and PLATFORM-APIS/README.md for the integration checklist.
Q: What's the test coverage requirement? A: See 2-FOR-ENGINEERS/testing-strategy.md — minimum 70% coverage, all critical paths at 90%+.

This documentation is a living resource. As systems evolve, so must their documentation.
Guidelines:
- Changes affecting multiple roles must maintain consistency
- Platform-specific docs must follow the standard template
- All content must be architecture/design documentation, not code
- See 4-COLLABORATION-GUIDE/contributing.md for detailed contribution process
- Version: 1.0.0 (Phase 1 — Initial Structure)
